This updated and revised guideline will assist contractors, NDE service providers, owners, design professionals, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE methods can be very useful to perform a condition assessment prior to repairs and to provide quality control and assurance of repairs and long-term performance monitoring. Considerations in planning and executing an NDE program, including correlating with destructive methods, are discussed in the guideline. Guidance, including a brief synopsis of each method, is presented for selecting which NDE methods are appropriate for the concrete property/condition being assessed.
This option is available for those who purchased the Certification course and completed the training Modules 1-5 and the knowledge exam — but failed one or more of the tests in the performance exam.

Short Description:
Este Lineamiento pretende ser una herramienta usada para educar a supervisores, trabajadores del oficio, propietarios e ingenieros sobre las prácticas de trabajo seguras en la industria de reparación de concreto. El lineamiento se ha desarrollado para ser una herramienta visual que representa el desempeño seguro de tareas específicas y los peligros asociados con ellas. Los requerimientos descritos aquí se basan en los estándares de OSHA más recientes y pretenden proporcionar una guía y capacitación en la planeación y ejecución de proyectos de reparación y restauración.
This guide is intended to provide an introduction to the techniques and procedures used to evaluate and repair existing concrete structures post-tensioned with unbonded single-strand tendons. This guide demonstrates how the strength and serviceability of a structure that has experienced deterioration can be evaluated and restored to its original—or greater—strength and serviceability. Post-tensioning design, evaluation, and repair requires specialized knowledge. There is no substitute for experience and knowledge in working with post-tensioned structures. An experienced contractor and licensed design professional team is essential when working with post-tensioned structures. [Replaces 210.2–2002 (Evaluation) AND 320.4–2006 (Repair)]
This comprehensive book describes the causes, effects, and remedies for concrete wear and failure. It is a practical guide to evaluation of deterioration and its causes, selection of repair methods and materials, surface preparation, and quality assurance of the finished product. Hundreds of illustrations show users how to analyze, maintain, and repair concrete structures for optimal performance and cost-effectiveness.
This guide specification aids the Design Professional in the preparation of technical specifications for inclusion directly into a project manual for the construction of cementitious bonded overlays that are in line with the state-of-the-art materials and methods used in the concrete repair industry. The document provides an outline for developing the three parts of the specification through suggested text, references, and commentary for evaluating alternatives. This specification section must be used with ICRI 110.1, Guide Specifications for Structural Concrete Repairs. Both the printed and PDF copies include a Word document with hidden text for easy modification of text to meet specific cementitious bonded overlay project requirements. PDF version is free to ICRI members when ordered online.
This special publication is a compilation of existing articles on various structural strengthening, stiffening, and stabilization topics, including external bonded reinforcement, external post-tensioning, internal post-tensioning, section enlargement and overlays, supplemental framing and span shortening, and strengthening and stabilization of masonry structures. The purpose is to provide engineers and contractors with a single-source overview of the various materials and techniques available to solve strengthening, stiffening, and stabilization problems. The wealth of information provided should provide invaluable “food for thought” to facilitate the strengthening, stiffening, and stabilization design process.
Este lineamiento proporciona una guía sobre la remoción de concreto y los procedimientos para la preparación de la superficie paray la reparación del de concreto deteriorado provocado por la corrosión del acero de refuerzo. Se discuten la geometría de la remoción, la configuración del área de reparación, el proceso de remoción, la preparación del borde, la reparación del refuerzo, la preparación e inspección de la superficie necesarias para las reparaciones durables. Se incluyen consideraciones especiales para la remoción de concreto asociada con la reparación de columnas.
Summarizes the capabilities, operating requirements, and limitations of the various methods used to prepare concrete surfaces for the application of protective sealers, coatings, polymer overlays, and concrete repair. Benchmark profiles are included which provide visual standards for purposes of specification, application, and verification. In this updated version of the guideline you will find; surface retarders and handheld breakers have been added to the surface preparation methods; surface preparation methods have been updated; and a new appendix summarizes considerations for selecting surface preparation methods and describes various test methods used to evaluate the prepared surface. Plus, concrete surface profile (CSP) 10 has been added to reflect a more aggressive CSP used for concrete repair.
Dans l'industrie de la construction, il est parfois difficile de spécifier les bons outils pour le mélange, l'application et la finition des matériaux de réparation. En effet, il n'est pas rare qu'un même terme désigne plusieurs outils et qu'à l'inverse, un même outil soit désigné par plusieurs termes. Or, il existe une grande variété de mélangeurs et de palettes de mélange, lesquels confèrent différentes consistances et propriétés aux matériaux de réparation. Le problème se présente aussi avec les mélangeurs mécaniques. Par exemple, le terme "malaxeur à mortier" peut être interprété de diverses manières. L'objectif de ce document n'est pas d'évaluer l'efficacité des outils offerts sur le marché, ni de favoriser l'emploi d'un outil plutôt qu'un autre; il vise simplement à offrir une référence terminologique commune et de source unique aux professionnels de la construction afin de faciliter la description ou la spécification des outils utilisés pour le mélange, l'application et la finit
